That is what the basis of packages is more or less. All code (including VMTs
etc) only existing once, and a initialization order that matches the
requirements of the unit initialization order.

IOW packages is just an automatable (for the compiler) of such system. More
like how you compile a mainprogram with the compiler in one go instead of
sorting the different .o's and passing cmds to the linker.
